And before you ask. No, we don't have a shot with him.
Now, if you were one of those pot stirrers you might say, oh I don't know.
You might say Mack "backed off" because of a recent knee injury RSJ suffered. Probably unfair of you because, even as slimy as we know him to be, Mack doesn't really have a history of this. But, hey, you're stirring the pot.
You might say Mack and his Texas sized ego were so bruised that they "backed off" because of his decommitment and subsequent delay in re-committing to the mighty Horns.
You might even say that Mack is so petty and so proud of his self proclaimed championship of offered vs. committed recruits that they "backed off" in order to claim "Hey, we backed off him" as opposed to the alternative. You know, that thing they call reality.
But again, you'd only say things such as these if you were looking to stir the pot. And that is definitely not what we're doing here.
